A wall is not possible with a coastline that long. Deportations, and keeping the migrant boats from lenading can be started tomorrow.
Let them starve, drown, beg, whatever...After the first hundred deaths, the news will be out there: The Euros mean business. No sense trying.
Even deportations are easy if you mean it. Give them a deadline with nasty consequences if they won't and they will self-deport.
Those "autocratic" places like China are looking better and better...
Some asked me why I am not in Moscow. Between Paris and Moscow... an easy call.
It will be safer there.
If not for my family here, I would already be there.
